Lions strive to answer Hellen Keller's call to be the knights of the Blind by serving the visually impaired. Today, 80% of vision impairments are preventable or curable, so our service is more important than ever before. We screen vision, educate our communities, build clinics and support the blind and visually impaired through assistive technology and vocational training programs. We work to preserve the precious gift of sight for the world.
